The unit rate of running 2.3 km in 7 minutes is 5.48 metres per second.

Unit rate can be defined as a measure used to represent how many units of one type of quantity corresponds to one unit of anther type of quantity.

Here the distance is given in kilometres (km) which can be converted into metres by multiplying by 1000 as,

2.3 km = 2.3*1000 metres

= 2300 metres

Here the time taken to cover 2.3 km is 7 minutes which can be converted ito seconds by multiplying by 60 as,

7 minutes= 7*60 seconds

= 420 seconds

Hence the unit rate of running 2.3 km in 7 minutes expressed in metre per second is calculated as = 2300 metres / 420 seconds

= 5.4761 metres per second

= 5.48 metres per second (approximately)

(2) The polynomials x^3 − k, where k = 0, 1, 2, 3, 4, 5, 6, are all irreducible in Z7[x].

(3) The polynomial x^4 − 1 can be factored into (x − 1)(x + 1)(x^2 + 1) in Z7[x].

This is because 5 and −5 are both roots of the polynomial, since 5^2 ≡ 2 (mod 7) and (−5)^2 ≡ 2 (mod 7).

This is because none of them have any roots in Z7, which means they cannot be factored into lower degree polynomials.

For example, x^3 − 0 has no roots in Z7, since there is no integer x such that x^3 ≡ 0 (mod 7). Similarly, x^3 − 1 has no roots in Z7, since there is no integer x such that x^3 ≡ 1 (mod 7), and so on for the other values of k.

This is because 1, −1, and ±i are all roots of the polynomial, since 1^4 ≡ 1 (mod 7), (−1)^4 ≡ 1 (mod 7), and (±i)^4 ≡ 1 (mod 7). Therefore, x^4 − 1 = (x − 1)(x + 1)(x^2 + 1) in Z7[x].

Height of a trapezoid with Pythagorean theorem is = √{Hypotenuse ^2 - Base ^2}

Trapezoid has two parallel sides and two non parallel sides. The length of the parallel sides are unequal but the length of the non parallel sides are equal.

Thus the trapezoid can be divided into three parts where one is rectangle ( which has length equal to the shortest length of the parallel sides) and two triangles which are equal ( having equal base, height and hypotenuse).

The Pythagoras theorem on the triangular part of the trapezoid can be stated as ,

Hypotenuse ^2 = Base ^2 + Height ^2

⇒ Height ^2 = Hypotenuse ^2 - Base ^2

⇒ Height = √{ Hypotenuse ^2 - Base ^2}

where, Height of the triangle is equal to that of the trapezoid it belongs to;

Hypotenuse of the triangle is the non parallel but equal side of the trapezoid;

Base of the triangle is = {(length of the longest side of parallel sides of trapezoid) -   (length of the shortest side of parallel sides of trapezoid) }/2

The answer is value of x when y=25 are 8.33.

The missing variable y varies directly with x, which means that y = kx, where k is a constant.

We can use this equation to find the value of k and then use it to find the value of x when y=25.

First, let's find the value of k:
y = kx
75 = k*25
k = 75/25
k = 3

Now that we know the value of k, we can use it to find the value of x when y=25:
y = kx
25 = 3x
x = 25/3
x = 8.33

Therefore, the value of x when y=25 is 8.33.

The polynomial  3x³ - 4x² + 9x - 12 as a product of binomials is (3x - 4)(x² + 3).

To rewrite the polynomial 3x³ - 4x² + 9x - 12 as a product of binomials, we need to factor the polynomial. One method to do this is by grouping. Here are the steps:

1. Group the first two terms and the last two terms: (3x³ - 4x²) + (9x - 12)
2. Factor out the common factor from each group: x²(3x - 4) + 3(3x - 4)
3. Notice that (3x - 4) is a common factor in both groups, so we can factor it out: (3x - 4)(x² + 3)
4. Now we have the polynomial rewritten as a product of binomials: (3x - 4)(x² + 3)

A polynomial of degree 3 that satisfies, we need to use the fact that if a polynomial has a zero at x = a, then (x - a) is a factor of the polynomial. So, for the given zeroes, we have the factors (x + 1/2), (x - 2), and (x - 3).

Multiplying these factors together, we get:

(x + 1/2)(x - 2)(x - 3) = (x^2 - (3/2)x - 1)(x - 3) = x^3 - (9/2)x^2 + (1/2)x + 3

To get a constant coefficient of 12, we need to multiply this polynomial by a constant. Since the current constant coefficient is 3, we need to multiply by 4:

4(x^3 - (9/2)x^2 + (1/2)x + 3) = 4x^3 - 18x^2 + 2x + 12

To find a linear function h(x) given two points, we can use the formula for the slope of a line:
m = (y2 - y1) / (x2 - x1)
Where m is the slope, (x1, y1) and (x2, y2) are the two points.

In this case, the two points are (-3, -4) and (-9, -5). Plugging in the values into the formula, we get:
m = (-5 - (-4)) / (-9 - (-3))
m = (-1) / (-6)
m = 1/6
Now that we have the slope, we can use the point-slope form of a linear equation to find the function h(x):
y - y1 = m(x - x1)
Plugging in the slope and one of the points, we get:
y - (-4) = (1/6)(x - (-3))
y + 4 = (1/6)(x + 3)
y = (1/6)x + 3/6 - 4
y = (1/6)x - 21/6

Simplifying the equation, we get:

Answer:

Gradient of A:    [tex]2[/tex]

Gradient of B :  [tex]- 1[/tex]

Step-by-step explanation:

Gradient of a line is the slope of the line

Slope = rise/run

rise = difference in y values between any two points on the line

run = difference in x values between the corresponding points

Line A

Take points (0, 1) and (3,7)
rise = 7 - 1 = 6
run = 3 - 0 = 3

slope = gradient = 6/3 = 2

Gradient of a line which goes diagonally up from left to right is positive

Line B

Take points (0,5) and (5, 0)

rise = 0 - 5  = - 5

run = 5 - 0 = 5

slope = gradient = -5/5 = - 1

Gradient of a line which goes diagonally down from left to right is negative

The two integers are 5 and 6.

To solve this problem, we need to set up an algebraic equation based on the information given.

Let's call the first integer x and the second integer y. According to the problem, an integer (x) is 14 less than 4 times another (y).

This can be written as: x = 4y - 14

We are also told that the product of the two integers is 30. This can be written as:

xy = 30

Now we can substitute the first equation into the second equation to solve for one of the variables.

Let's solve for y:

(4y - 14)y = 30

4y^2 - 14y = 30

4y^2 - 14y - 30 = 0

Using the quadratic formula, we can solve for y:

y = (-(-14) ± √((-14)^2 - 4(4)(-30)))/(2(4))

y = (14 ± √(196 + 480))/8

y = (14 ± √676)/8

y = (14 ± 26)/8

y = 5 or y = -1.5

Now we can plug these values of y back into the first equation to find the corresponding values of x:

x = 4(5) - 14 = 6

x = 4(-1.5) - 14 = -20

So the two integers are either 5 and 6, or -1.5 and -20. However, since the problem asks for integers, we can eliminate the second solution.

Therefore, the two integers are 5 and 6.

Answer: To obtain the relation between α and β, we can eliminate t from the given equations.

(iv)

α = 1/2a(t+1/t)

β = 1/2a(t-1/t)

We can multiply these two equations to eliminate t^2:

αβ = (1/2a(t+1/t))(1/2a(t-1/t))

αβ = (1/4a^2)(t^2 - 1/t^2)

Multiplying both sides by 4a^2 gives:

4a^2αβ = t^2 - 1/t^2

Adding 1/t^2 to both sides gives:

4a^2αβ + 1/t^2 = t^2 + 1/t^2

Multiplying both sides by t^2 gives:

4a^2αβt^2 + 1 = t^4 + 1

Rearranging and simplifying gives the relation between α and β:

4a^2αβ = t^4 - 4a^2t^2 + 1

Now we can write the locus of the point as t varies:

4a^2αβ = t^4 - 4a^2t^2 + 1

This is a fourth degree equation in t, which represents a curve in the (α, β) plane. However, we can simplify it by noting that t^2 is always non-negative. Therefore, we can treat 4a^2t^2 as a constant and write:

4a^2αβ = (t^2 - 2a^2)^2 + 1 - 4a^4

we will evaluate the expression at the lower limit of integration, t = 0:
[(7)/(3)(0)^((3)/(2))-(1)/(5)(0)^((5)/(2))] = [(7)/(3)(0)-(1)/(5)(0)] = 0
